Bathroom Window Exhaust Fan Winter

Venting a bathroom with a window fan in the winter? I'm looking to replace our window mounted bathroom exhaust fan as it is not well insulated and therefore means the bathroom is getting increasingly cold in the winter. We have no heater in there in any case. In this Q.

The difference is that you can't leave the vent fan in the window all the time, because obviously it will let cold air in from outside.
